Interturn short circuit is a common cause of engine combustion. But it can be prevented. Let's look at prevention of interturn short circuit.
Why a short circuit occurs
An interturn short circuit is a breakdown of the insulation between adjacent turns of the winding. The main reasons are overheating, insulation aging, overvoltage and vibration.
Preventive measures
- Overheat control. Clean ventilation, overload protection - overheating is the main enemy of insulation.
- Overvoltage protection. Power surges damage interturn insulation.
- Quality impregnation. During rewinding good impregnation protects the turns from chafing.
- Reduction of vibration. Balancing and alignment.
- Regular diagnostics. Early detection of reduced insulation.
How to detect early stage
| Method | What it shows |
|---|---|
| Measurement of phase resistance | Distortion during an incipient short circuit |
| Thermal imager | Local overheating |
| Measurement of current phases | Asymmetry |
Early detection allows you to plan repairs before sudden combustion. Regular diagnosis is the best prevention. Proper operation without overheating extends the life of the winding for years.
